OPERATING TABLE.

' Application filed I111y29, 1926. Serial No. 125,663..

My invention relates to folding tables, particularly adapted for use in veterinary operations. It is my object to provide ata'ble ofsuch shape that a pig or other animal may I be securely held on the table with little etfort.

More particularly, it is my object to provide a table having a trough orV-shaped top between thesides of which the animal 1 maybe placed in inverted position.

A further object is to provide legs for supporting' the table, thelegs being foldable against the sides or the top members of the table towform a compact package.

Another object is to provide a strap in connection with the topfior holding thenose of an animal, said strap serving also to hold the legs; in folded position if desired.

A still further object of my invention is to provide legs so arranged that when in supporting position a pair of crossed legs secured to one member of the top cross a pair of crossed legs secured to the' other member of the top in such a manner that a chain may be secured between; the pairs of legs at their individual crossing points and serve to regulate thedistance between the pairs of legs and consequentlythe height of thetable.

A further object is to provide a hinge connection between the individual legs of each pair of legs which will allow them to fold to most compact position against the top members.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts or my device, whereby the objects con templated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanyingdrawings, in which: 0

Fig. 8 is an end view of the table folded.

I have used the reference character 10 to illustrate a sidermember of the top, formed of a plank of suitable proportions. There The ends of the bifurcated portion 16 are bent inwardly as at 17. A stud 18 is secured inthe top member 10 inposition to be received. by the bifurcated portion 16, and a nut 19 1's threaded onto the stud 18 to secure the hook 15. lnorder to 'removethe hook from the stud, the nut must bev threaded away from the bifurcated portion 16 sutli ciently to clear the hooked ends 17 L Each pair of legs is crossed and secured. together, by means of a hinge as shown in Fig. 5. riety, having the two leaves 20 and 21. The leaf 20 is secured to the leg l t and the leaf 21 is pivoted by means of a bolt 22 to'thelleg 12. Thepivot 22. allows the leg 14 to swing from the position shown in Figs. 1 to 3, and in dotted lines. in Fi 6, in the common plane of the legs, of the particular pair to the position shown in full lines inf'Fig. 6. The

pivot 23 then allows the leg 1 11 to hinge about the leg 12. to the posit-ionv shown in full lines in Fig. 7. From thence the two legs may be swung to the position shown in dotted lines in'Fig. 7 and in full lines in 8.

of the pair 11,.and in collapsing the table, the pair B is first folded;

In order to do this, the leg 14 is first unhooked from. its top member, is swung to the position shown in full lines in Fig. 6, and the pair of legs'then swung to a position substantially perpendicular to the lower edge o'lf the top member, in. order to clear the end of the leg 14 of the pair A. The

The hinge isot' an ordinary vaa The legs otthe pair B embraceithe legs r top members are then collapsedtogether,

uncrossing the two pairs of legs. The respective pairs may then be folded as previously described, to the. pos tions shown in T g Without the hinge pivot 23, the legs could still be collapsed, against the sides of the top members, but would stand out one upon I provide a strap 25, received through slots 26 in the top members 10.

In using thetable, the height is adjusted by moving the pairs of legs toward or from each other, and they are then secured by a chain 27 linked between them as shown. By shortening the chain, the height of the table will be raised, as will readily be seen.

In working on large animals, it is desirable to have the table lower, to facilitate handling the animal, and the top members are correspondingly spread at a greater angle to accommodate the widerback of the animal. For small animals. the work may be more easily performed with the table at a greater lieighhand the top members are correspondingly brought closer together by raising the top, to more securely receive the narrower back of the animal.

The animal is placed on its back in the trough as indicated by dotted lines in Fig. 1. The strap 25 is then placed over the jowl of the animal, the hind leg held by one person and the hypodermic needle or knite handled by another. Ordinarily several men are required just to hold the animal. With my device the animal may be held with ease by one man and held in such a way that he cannot move.

The strap 25 may be employed as indicated in Fig. 8, if desired, to secure the legs in folded positions.

By extending the ends of the legs 12 beyond the pivots 13 as shown in Fig. 2, the top members are braced against spreading.

It will be seen that the greater the weight upon the table, the more firmlybraced will the legs become.

Some changes may be made in the construction and arrangement of the parts of my invention, without departing from the real spirit and purpose of "my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:

1. In an operating table, two top members hinged together to form a trough, a pair of legs secured to each member and secured together in crossed relation, the respective pairs crossing each other above the points where the legs of those pairs are secured together and a flexible element extending between the pairs and looped around the pairs where the legs of those pairs cross each other, said flexible element being secured upon itself at one of several possible positions along its length to thereby form a loop of variable dimensions for tying the pairs together against outward pressure caused therebetween by downward pressure upon thetrough.

2. In an operating table, two top members hinged together to form a trough, a pair and adjustable means connecting the pairs and positioned between their pivot points whereby downward pressure imposed between the members of the trozjigh will rigidity the legs in their relation tocach other and the trough.

3. In an operating table, a pair of top members hinged together to form a troilgh, a pair of crossed legs secured to each memher, the legs of each pair being pivoted together on an axis perpendicular to the legs, hooks secured to the upper end of: one of the legs of each pair, studs secured to the top members and received by said hooks and nuts threaded onto the studs to secure the hooks thereto.

a. In an operating table, a pair of top members hinged together to form a trough, a pair of crossed legs secured to each member, the legs of each pair being pivoted together on an axis perpendicular to the legs, hooks secured to the upper end or one of the legs of each pair, studs secured to the top members and received by said hooks and nuts threaded onto the studs to secure the hooks, the hooks having inwardly bent portions to lock them against removal from the studs when the nuts are threaded down against the hooks.

In an operating table, a pair of top members hinged together to form a trough, a pair of crossed legs secured to each memher, the legs of each pair being pivoted together on an axis iier iendicular to the legs. a hinge allowing the legs to more on a scoondaxis parallel to the legs, said hinge be ing secured to one of the legs and pivoted to the other leg to provide said pivotal con nection therebetween, one oi the legs of each pair being detachable fron'l its top n'leinber to allow folding of the pair of legs side by side against the top member.

6. In an ope 'ating table, a pair of: too membershinged' together to form a trough, a pair of crossed legs secured to each memher, the legs of each pair being pivoted together where they cross, on an axis perpendicular to the legs. one of the legs of each pair being detachable from its top member to allow folding of the pair of legs side by side against the top member.

7. In an operating table, a pair 0'[ top members hinged together to l'orm a trough, a pair of crossed legs secured to each member. the legs of each pair being pivotedtrt gether on an axis perpendicular to and on a second axis parallel to, the legs. one of the legs of each pair being detachable from its top memliier to allow tolding of the pair of legs side by side against the top member.
